    Abstract: In a multiprocessing system, multiple concurrently operating task execution units are operated to perform an aggregate task by using incremental and on-demand sub-task allocation. A command is received to perform a machine-executed task divisible into multiple sub-tasks, i.e., an “aggregate task”. A granularity is then established, for dividing the aggregate task into sub-tasks. Preferably, the granularity is not too large to permit potentially uneven sub-task allocation, and not too small to incur excessive overhead in allocating sub-tasks. Having established the granularity, multiple task execution units are independently operated on-demand to sequentially self-allocate and execute sub-tasks of the aggregate tasks. Each sub-task is sized according to the established granularity. Operating “on-demand”, each task execution unit sequentially allocates and executes one sub-task at a time, then proceeding to the next unexecuted sub-task. Thus, the multiprocessing system operates like multiple people drinking water from a common glass through individual straws—although each drinker works independently, all finish simultaneously, thus completing the aggregate task as expeditiously as possible.

    Abstract: Alkylene oxide polymer compositions having particular molecular weight distributions are disclosed. As a result of the molecular weight distributions, the disclosed alkylene oxide polymer compositions are suitable, among other things, for the manufacture of films, e.g., for use in manufacturing soft gel capsules. Capsules made from the disclosed alkylene oxide polymer compositions can provide enhanced resistance to crosslinking often caused by liquid filling materials, e.g., polyethylene glycol, used in gelatin capsule manufacture.
